Detailed ways

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present application, and should not be construed as a limitation on the present application.

Referring to FIG. 1 , an electronic device 1000 according to an embodiment of the present application includes a casing 110 and a camera assembly 100 . The camera assembly 100 is exposed through the casing 110 .

Exemplarily, the electronic device 1000 may be any one of various types of computer system devices that are mobile or portable and perform wireless communication (only one form is exemplarily shown in FIG. 1 ).

Specifically, the electronic device 1000 may be a mobile phone or a smart phone (eg, a phone based on an iPhone system (Apple system), a phone based on an Android system (Android system)), a portable game device (eg, an iPhone (Apple phone)), a laptop Computers, personal digital assistants (PDAs), portable Internet devices, music players and data storage devices, other handheld devices and devices such as watches, in-ear headphones, pendants, headphones, and the like.

The electronic device 100 may also be other wearable devices (eg, a head mount display (HMD) such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices or smart watches).

The casing 110 is an external part of the electronic device 1000 , and plays a role of protecting the internal parts of the electronic device 1000 . The casing 110 may be a back cover of the electronic device 1000 , and the back cover covers components such as a battery of the electronic device 1000 .

In this embodiment, the camera assembly 100 is rear-mounted, or in other words, the camera assembly 100 is disposed on the back of the electronic device 1000 so that the electronic device 1000 can perform rear-facing photography. In the example of FIG. 1 , the camera assembly 100 is disposed at the upper middle position of the casing 110 .

Of course, it can be understood that the camera assembly 100 may be arranged at other positions such as the upper left position or the upper right position of the casing 110 . The position where the camera assembly 100 is disposed on the casing 110 is not limited to the examples of the present application.

Referring to FIG. 2 , the camera assembly 100 includes a first imaging module 20 , a second imaging module 30 , a third imaging module 40 and a bracket 50 .

The first imaging module 20 , the second imaging module 30 and the third imaging module 40 are all disposed in the bracket 50 and fixedly connected to the bracket 50 . The bracket 50 can reduce the impact on the first imaging module 20 , the second imaging module 30 and the third imaging module 40 , and improve the service life of the first imaging module 20 , the second imaging module 30 and the third imaging module 40 .

In this embodiment, the field of view angle FOV3 of the third imaging module 40 is greater than the field of view angle FOV1 of the first imaging module 20 and smaller than the field of view angle FOV2 of the second imaging module 30 , that is, FOV1 < FOV3 <FOV2. In this way, the three imaging modules with different viewing angles enable the camera assembly 100 to meet shooting requirements in different scenarios.

In one example, the field of view angle FOV1 of the first imaging module 20 is 10-30 degrees, the field of view angle FOV2 of the second imaging module 30 is 110-130 degrees, and the field of view angle FOV3 of the third imaging module 40 80-110 degrees.

For example, the field of view angle FOV1 of the first imaging module 20 is 10 degrees, 12 degrees, 15 degrees, 20 degrees, 26 degrees, or 30 degrees. The field of view angle FOV2 of the second imaging module 30 is 110 degrees, 112 degrees, 118 degrees, 120 degrees, 125 degrees or 130 degrees. The field of view angle FOV3 of the third imaging module 40 is 80 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees, or 110 degrees.

Since the field of view FOV1 of the first imaging module 20 is relatively small, it can be understood that the focal length of the first imaging module 20 is relatively large. Therefore, the first imaging module 20 can be used for shooting long-range images, so as to obtain images with clear long-range views. . The field of view FOV2 of the second imaging module 30 is relatively large. It can be understood that the focal length of the second imaging module 30 is relatively short. Therefore, the second imaging module 30 can be used to capture close-up shots to obtain local close-up images of objects. The third imaging module 40 can be used to photograph objects normally.

In this way, through the combination of the first imaging module 20 , the second imaging module 30 and the third imaging module 40 , image effects such as background blur and partial picture sharpening can be obtained.

The second imaging module 30 is disposed close to the first imaging module 20 . The third imaging module 40 is disposed close to the second imaging module 30 . The second imaging module 30 is disposed between the first imaging module 20 and the third imaging module 40 .

The first imaging module 20 , the second imaging module 30 and the third imaging module 40 are arranged side by side. In this embodiment, the first imaging module 20 , the second imaging module 30 and the third imaging module 40 are arranged in an L-shape.

Due to the angle of view of the first imaging module 20 and the third imaging module 40, in order to obtain better quality images from the first imaging module 20 and the third imaging module 40, the first imaging module 20 and the third imaging module 40 The three imaging modules 40 may be configured with an optical anti-shake device, and the optical anti-shake device is generally configured with many magnetic elements, so the first imaging module 20 and the third imaging module 40 can generate a magnetic field.

In this embodiment, the second imaging module 30 is located between the first imaging module 20 and the third imaging module 40, so that the first imaging module 20 and the third imaging module 40 can be far away, preventing the first imaging The magnetic field formed by the module 20 and the magnetic field formed by the third imaging module 40 interfere with each other and affect the normal use of the first imaging module 20 and the third imaging module 40 .

The arrangement of the first imaging module 20 , the second imaging module 30 and the third imaging module 40 in an L shape may mean that the first plane formed by the imaging optical axis and the light entrance axis of the first imaging module 20 is the same as the first plane. The second plane formed by the light entrance axis of the second imaging module 30 and the light entrance axis of the third imaging module 40 is substantially perpendicular; it can also refer to the first imaging module 20, the second imaging module 30 and the third imaging module The connection line of the center point of the light inlet of 40 is "L" shape.

In other embodiments, the first imaging module 20 , the second imaging module 30 and the third imaging module 40 are arranged along the same straight line.

The arrangement of the first imaging module 20 , the second imaging module 30 and the third imaging module 40 along the same straight line may mean that the first plane formed by the imaging optical axis and the light entrance axis of the first imaging module 20 is the same as the first plane. The light entrance axis of the second imaging module 30 and the second plane formed by the light entrance axis of the third imaging module 40 are coplanar.

The first imaging module 20 , the second imaging module 30 and the third imaging module 40 may be arranged at intervals, and two adjacent imaging modules may also abut against each other.

In the first imaging module 20, the second imaging module 30 and the third imaging module 30, any imaging module can be a black and white camera, an RGB camera or an infrared camera.

It should be pointed out that the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined as "first", "second" may expressly or implicitly include one or more of said features. In the description of the present application, "plurality" means two or more, unless otherwise expressly and specifically defined.

Referring to FIGS. 3-5 , in this embodiment, the first imaging module 20 includes a periscope lens 10 , a housing 21 , a first lens assembly 24 , a loading element 25 , a first image sensor 26 , a driving mechanism 27 and a driving device 28.

The first lens assembly 24 and the loading element 25 are both arranged in the housing 21 . The first lens assembly 24 is fixed on the loading element 25 . The loading member 25 is provided on the side of the first image sensor 26 . Further, the loading element 25 is located between the periscope lens 10 and the first image sensor 26 .

The drive mechanism 27 connects the loading element 25 with the housing 21 . After the incident light enters the first imaging module 20 , it is turned through the periscope lens 10 , and then passes through the first lens assembly 24 to reach the first image sensor 26 , so that the first image sensor 26 obtains an external image. The driving mechanism 27 is used to drive the loading member 25 to move along the optical axis of the first lens assembly 24 to make the first lens assembly 24 focus and image on the first image sensor 26 .

Referring to FIG. 6 and FIG. 7 , in this embodiment, the periscope lens 10 includes a lens barrel 11 , a light converting element 12 and a two-axis hinge 13 . The light converting element 12 is provided in the lens barrel 11 . The light diverting element 12 is used to turn the light from the light entrance axis 101 to the imaging optical axis 102 , and the imaging optical axis 102 is perpendicular to the light entrance axis 101 . The two-axis hinge 13 rotatably connects the lens barrel 11 and the light converting element 12 . The two-axis hinge 13 includes a first rotating shaft 103 and a second rotating shaft 104 , the first rotating shaft 103 is perpendicular to the light entrance axis 101 and the imaging optical axis 102 , and the second rotating shaft 104 is a second rotating shaft 104 parallel to the light entrance axis 101 .

In this way, through the first rotating shaft 103 and the second rotating shaft 104 of the two-axis hinge 13, the light turning element 12 can be rotated in two directions, and the rotation accuracy of the light turning element 12 is high, so that the camera with the periscope lens 10 Better optical image stabilization can be achieved in both directions. In addition, the structure of the two-axis hinge 13 is compact, and the volume of the periscope lens 10 can be reduced.

It can be understood that the first imaging module 20 is a periscope lens module. Compared with the vertical lens module, the height of the periscope lens module is smaller, so that the overall thickness of the electronic device 1000 can be reduced. The vertical lens module means that the imaging optical axis and the light entrance axis of the lens module are in a straight line. In other words, the incident light is transmitted to the photosensitive device of the lens module along the direction of a linear optical axis.

It should be pointed out that the light entering from the light entrance axis 101 refers to the light entering the periscope lens 10 with the light entrance axis 101 as the center. formed at a certain angle.

In addition, the light turning to the imaging optical axis 102 refers to the light propagating with the imaging optical axis 102 as the center.

Specifically, the lens barrel 11 is substantially in the shape of a square. The lens barrel 11 can be made of plastic, metal and other materials. The lens barrel 11 has a light inlet 211 , and incident light enters the periscope lens 10 from the light inlet 211 . That is to say, the light diverting element 12 is used to turn the incident light incident from the light inlet 211 and transmit it to the first image sensor 26 through the first lens assembly 24 so that the first image sensor 26 can sense the first imaging mode. Incident light outside of group 20.

Referring to FIGS. 4 and 6 , the lens barrel 11 includes a top wall 213 , a side wall 214 and a bottom wall 216 . The side wall 214 is formed to extend from the side edge 2131 of the top wall 213 . The bottom wall 216 is opposite to the top wall 213 . The top wall 213 is formed with a light inlet 211 , or in other words, the light inlet 211 is formed on the top wall 213 . The top wall 213 includes two opposite sides 2131 . The number of side walls 214 is two, and each side wall 214 extends from a corresponding side edge 2131 . In other words, the side walls 214 are respectively connected to opposite sides of the top wall 213 .

The light converting element 12 includes a light converting portion 22 and a mounting portion 23 , and the light converting portion 22 is arranged on the mounting portion 23 . The light diverting portion 22 can be fixed on the mounting portion 23 by adhesive bonding to realize the fixed connection with the mounting portion 23 .

The light converting portion 22 is a prism or a plane mirror. In one example, when the light converting portion 22 is a prism, the prism can be a triangular prism, and the cross-section of the prism is a right-angled triangle, wherein the light is incident from one of the right-angled faces of the right-angled triangle, and then reflected from the other right-angled face. out.

Of course, the incident light can be refracted by the prism and then exit without being reflected. The prism can be made of materials with relatively good light transmittance such as glass and plastic. In one embodiment, one surface of the prism may be coated with a reflective material such as silver to reflect incident light.

It can be understood that when the light turning part 22 is a flat mirror, the flat mirror reflects the incident light so as to realize the turning of the incident light.

For more details, please refer to FIG. 6 and FIG. 8 , the light converting portion 22 has a light incident surface 222 , a backlight surface 224 , a light converting surface 226 and a light exit surface 228 . The light incident surface 222 is close to and faces the light inlet 211 . The backlight surface 224 is away from the light inlet 211 and is opposite to the light incident surface 222 . The light transfer surface 226 is connected to the light incident surface 222 and the backlight surface 224 . The light-emitting surface 228 is connected to the light-incident surface 222 and the backlight surface 224 . The light exit surface 228 faces the first image sensor 26 . The light deflecting surface 226 is inclined with respect to the light incident surface 222 . The light exit surface 228 is disposed opposite to the light transfer surface 226 .

Specifically, during the turning process of the light, the light passes through the light inlet 211 and enters the light turning portion 22 from the light incident surface 222, then turns through the light turning surface 226, and finally reflects out of the light turning portion 22 from the light exit surface 228, completing the process. The process of turning light. The backlight surface 224 and the mounting portion 23 are fixedly arranged to keep the light converting portion 22 stable.

As shown in FIG. 9 , in the related art, due to the need to reflect incident light, the light-turning surface 226a of the light-turning portion 22a is inclined with respect to the horizontal direction, and the light-turning portion 22a has an asymmetric structure in the reflection direction of the light. Therefore, the actual optical area below the light converting portion 22a is smaller than that above the light converting portion 22a. It can be understood that the part of the light redirecting surface 226a away from the light inlet is less or unable to reflect light.

Therefore, referring to FIG. 10 , the light converting portion 22 according to the embodiment of the present application has cut edges and corners away from the light inlet relative to the light converting portion 22 a in the related art, which not only does not affect the effect of the reflected light of the light converting portion 22 , but also The overall thickness of the light converting portion 22 is reduced.

Referring to FIG. 6 again, the angle α of the light turning surface 226 relative to the light incident surface 222 is inclined at 45 degrees. In this way, the incident light is better reflected and converted, and has a better light conversion effect.

Further, the light converting portion 22 may be made of materials with relatively good light transmittance, such as glass and plastic. In one embodiment, a reflective material such as silver may be coated on one surface of the light converting portion 22 to reflect incident light. Of course, the light turning part 22 can realize the turning of incident light by utilizing the principle of total light reflection. In this case, it is not necessary to coat the light-reflecting material on the light-converting portion 22 .

In the example of FIG. 6 , the light incident surface 222 is arranged in parallel with the backlight surface 224 . In this way, when the backlight surface 224 and the mounting portion 23 are fixedly arranged, the light converting portion 22 can be kept stable, the light incident surface 222 also appears as a flat surface, and the incident light in the conversion process of the light converting portion 22 also forms a regular light path, so that the The conversion efficiency of light is better.

Specifically, along the light incident direction of the light inlet 211 , the cross section of the light diverting portion 22 is substantially trapezoidal, or in other words, the light diverting portion 22 is substantially trapezoidal. In the example of FIG. 6 , the light incident surface 222 and the backlight surface 224 are both perpendicular to the light exit surface 228 . In this way, a relatively regular light converting portion 22 can be formed, so that the light path of the incident light is relatively straight, and the conversion efficiency of the light is improved.

In one example, the distance between the light incident surface 222 and the backlight surface 224 is in the range of 4.8-5.0 mm. For example, the distance between the light incident surface 222 and the backlight surface 224 may be 4.85 mm, 4.9 mm, 4.95 mm, or the like. In other words, the range of the distance between the light incident surface 222 and the backlight surface 224 can be understood as that the height of the light converting portion 22 is 4.8-5.0 mm.

The light converting portion 22 formed by the light incident surface 222 and the backlight surface 224 within the above distance ranges is moderate in volume, and can be well fitted into the first imaging module 20 to form a more compact and miniaturized first imaging module 20 , the camera assembly 100 and the electronic device 1000 to meet more demands of consumers.

Optionally, the light incident surface 222 , the backlight surface 224 , the light transfer surface 226 and the light exit surface 228 are all hardened to form a hardened layer.

When the light-converting part 22 is made of materials such as glass, the material of the light-converting part 22 itself is relatively brittle. The surface 226 and the light-emitting surface 228 are hardened. Furthermore, all surfaces of the light converting element 12 can be hardened to further improve the strength of the light converting element 12 .

Further, the hardening treatment may be to infiltrate lithium ions, or to stick films on the above surfaces without affecting the light conversion of the light converting portion 22 .

In one example, the angle by which the light diverting portion 22 diverts the incident light incident from the light inlet 211 is 90 degrees. For example, the incident angle of the incident light on the emitting surface of the light converting portion 22 is 45 degrees, and the reflection angle is also 45 degrees. Of course, the angle at which the light turning portion 22 turns the incident light can also be other angles, such as 80 degrees, 100 degrees, etc., as long as the incident light can be turned to reach the first image sensor 26 .

In this embodiment, the number of the light diverting parts 22 is one. In this case, the incident light is diverted once and then transmitted to the first image sensor 26 . In other embodiments, the number of the light diverting parts 22 is multiple. In this case, the incident light is diverted at least twice and then transmitted to the first image sensor 26 .

The mounting portion 23 is used to mount the light converting portion 22 , or in other words, the mounting portion 23 is a carrier of the light converting portion 22 . The light diverting portion 22 is fixed to the mounting portion 23 . In this way, the position of the light turning portion 22 can be determined, which is beneficial to the reflection or refraction of the incident light by the light turning portion 22 .

Specifically, referring to FIG. 4 , in this embodiment, the mounting portion 23 is provided with a limiting structure 232 , and the limiting structure 232 is connected to the light converting portion 22 to limit the position of the light converting portion 22 on the mounting portion 23 .

In this way, the limiting structure 232 limits the position of the light converting portion 22 on the mounting portion 23 , so that the light converting portion 22 does not shift in position under impact, which is beneficial to the normal use of the first imaging module 20 .

It can be understood that, in an example, the light converting portion 22 is fixed on the mounting portion 23 by bonding. If the limiting structure 232 is omitted, then when the first imaging module 20 is impacted, if the light converting portion 2222 is connected to the mounting portion 23 The adhesive force between the parts 23 is insufficient, and the light diverting part 22 is easily detached from the mounting part 23 .

In this embodiment, the mounting portion 23 is formed with an accommodating groove 233 , the light-converting portion 22 is disposed in the accommodating groove 233 , and the limiting structure 232 is disposed on the edge of the accommodating groove 233 and abuts against the light-converting portion 22 .

In this way, the accommodating groove 233 can make it easy to install the light diverting portion 22 on the mounting portion 23 . The limiting structure 232 is arranged on the edge of the accommodating groove 233 and abuts against the edge of the light-converting part 22 , which can not only limit the position of the light-converting part 22 , but also prevent the light-converting part 22 from emitting incident light to the first image sensor. 26.

Further, the limiting structure 232 includes a protrusion 234 protruding from the edge of the accommodating groove 233 , and the protrusion 234 abuts against the edge of the light emitting surface 228 .

Since the light-converting portion 22 is mounted on the mounting portion 23 through the light-converting surface 226 , the light-exiting surface 228 is disposed opposite to the light-converting surface 226 . Therefore, when the light diverting portion 22 is impacted, it is more likely to generate a position toward the side of the light exit surface 228 . In this embodiment, the limiting structure 232 abuts against the edge of the light emitting surface 228 , which not only prevents the light turning portion 22 from being displaced toward the light emitting surface 228 , but also ensures that light exits from the light emitting surface 228 normally.

Of course, in other embodiments, the limiting structure 232 may include other structures as long as the position of the light diverting portion 22 can be limited. For example, the limiting structure 232 is formed with a slot, and the light-converting portion 22 is formed with a limiting column, and the limiting column is engaged in the slot to limit the position of the light-shifting portion 22 .

In this embodiment, the protrusions 234 are strip-shaped and extend along the edge of the light-emitting surface 228 . In this way, the contact area between the protrusion 234 and the edge of the light-emitting surface 228 is large, so that the light-converting portion 22 can be more stably located on the mounting portion 23 .

Of course, in other embodiments, the protrusions 234 may also have other structures such as blocks.

It can be understood that the mounting portion 23 can drive the light converting portion 22 to rotate in the opposite direction of the shaking of the first imaging module 20, thereby compensating for the incident light deviation of the light inlet 211 and realizing the effect of optical anti-shake.

In this way, the first rotating member 16 and the second rotating member 17 can realize the rotation of the light turning element 12 in two directions. Specifically, the first rotating member 16 is formed with a first rotating shaft 103 , so that the light rotating element 12 can rotate around the first rotating shaft 103 through the connecting member 14 .

Referring to FIGS. 4-6 , for the convenience of description, the width direction of the first imaging module 20 is defined as the X direction, the height direction is defined as the Y direction, and the length direction is defined as the Z direction. Thus, the light entrance axis 101 extends along the Y direction, the imaging optical axis 102 extends along the Z direction, the first rotation axis 103 extends along the X direction, and the second rotation axis 104 extends along the Y direction.

That is to say, the light converting element 12 can be rotated around the X direction by the first rotating member 16, so that the first imaging module 20 can realize the optical anti-shake in the Y direction. In addition, the light converting element 12 can be rotated around the Y direction by the second rotating member 17, so that the first imaging module 20 can achieve optical anti-shake in the X direction.

As shown in FIGS. 6 and 7 , in this embodiment, the connecting member 14 and the lens barrel 11 together define a first receiving space 141 , and the first rotating member 16 is disposed in the first receiving space 141 . In addition, the light converting element 12 and the connecting member 14 together define a second accommodating space 142 , and the second rotating member 17 is disposed in the second accommodating space 142 . The first accommodating space 141 and the second accommodating space 142 can make the structure of the two-axis hinge 13 more compact, thereby reducing the volume of the periscope lens 10 .

Specifically, the connecting member 14 and the side wall 214 together define the first receiving space 141 . The connecting member 14 and the mounting portion 23 together define a second receiving space 142 . The first accommodating space 141 and the second accommodating space 142 may be cylindrical or spherical or the like.

The first rotating member 16 rotatably connects the side wall 214 and the connecting member 14 . The first rotating member 16 includes rollers and/or balls. That is to say, the first rotating member 16 may be a roller or a ball, or the first rotating member 16 may include a roller and a ball. Understandably, the rollers are elongated. Balls are spherical. The first rotating member 16 can be made of metal or plastic. In order to reduce the frictional force of the first rotating member 16 , the surface of the first rotating member 16 may be provided with a film layer made of low friction coefficient such as polytetrafluoroethylene.

The number of the first rotating members 16 is multiple, and the plurality of first rotating members 16 are arranged at intervals along the first rotating shaft 103 .

Please refer to FIG. 6 and FIG. 7 again, further, the periscope lens further includes a driving device 28 , and the driving device 28 is used to drive the mounting portion 23 with the light-reversing portion 22 to rotate around the first rotating shaft 103 and the second rotating shaft 104 .

In this way, the driving device 28 drives the mounting portion 23 to move in two directions, which can not only achieve the optical anti-shake effect of the first imaging module 20 in two directions, but also make the first imaging module 20 smaller in size.

The driving device 28 drives the mounting part 23 to rotate, so that the light-turning part 22 rotates around the X direction, so that the first imaging module 20 can achieve the effect of optical anti-shake in the Y direction. In addition, the driving device 28 drives the mounting portion 23 to move along the axial direction of the rotation axis 29 , so that the first imaging module 20 achieves the effect of X-direction optical image stabilization. Additionally, the first lens assembly 24 may be along the Z direction to enable the first lens assembly 24 to focus on the first image sensor 26 .

Specifically, when the light turning part 22 rotates around the X direction, the light reflected by the light turning part 22 moves in the Y direction, so that the first image sensor 26 forms different images in the Y direction to achieve the anti-shake effect in the Y direction. When the light diverting part 22 moves along the X direction, the light redirected by the light diverting part 22 moves in the X direction, so that the first image sensor 26 forms different images in the X direction to realize the anti-shake effect in the X direction.

6-7 and FIG. 11 again, the driving device 28 includes an induction element 281 , a first electromagnetic element 282 , a third magnetic element 283 , a driving circuit board 285 , a second electromagnetic element 286 and a fourth magnetic element 287 .

The induction element 281 is disposed outside the first electromagnetic element 282 . The sensing element 281 is used to detect the rotation angle of the light converting portion 22 . The first electromagnetic element 282 is disposed on the side of the light converting portion 22 . The first electromagnetic element 282 is used to drive the light converting part 22 to rotate according to the data detected by the sensing element 281 , so that the first imaging module 20 can realize optical anti-shake.

Further, the first electromagnetic element 282 is used to drive the mounting portion 23 to rotate according to the data detected by the sensing element 281 to drive the light-turning portion 22 to rotate.

Optionally, the sensing element 281 is a Hall sensor, the first electromagnetic element 282 is a coil, and the third magnetic element 283 is a permanent magnet.

In this way, the inductive element 281 is disposed outside the first electromagnetic element 282. When the position of the inductive element 281 is shifted during the assembly process, it is possible to avoid a large deviation of the detected inductive data, while ensuring that the inductive element 281 normally participates in optical image stabilization. , the accuracy of the data collected by the sensing element 281 can be improved, and the accuracy of optical image stabilization can be improved.

In the related art, the Hall sensor is generally arranged in the center of the coil, so that the initial value of the Hall sensor is 0, so that the range of the Hall sensor is maximized. However, in the process of assembling each component, the position of the component will shift, resulting in errors in the data measured by the Hall sensor. For example, the Hall sensor is set in the center of the coil, and the initial value of the Hall sensor is 0mv. After assembly, the deviation of the position causes the Hall sensor to actually have a deviation of 10mv. At this time, the influence of the deviation is 100%.

However, if the Hall sensor is arranged outside the coil, the Hall sensor forms a non-zero initial value, which can reduce the influence of deviation. For example, after placing the Hall sensor on the outside of the coil, the initial value of the Hall sensor is 140mv. After assembly, the deviation of the position causes the Hall sensor to actually have a deviation of 10mv. At this time, the influence of the deviation is 7%.

It is defined that the U direction is the direction in which the light converting portion 22 moves along the X direction, and the V direction is the direction that the light converting portion 22 rotates around the X direction.

Referring to FIGS. 12 and 13 , it is defined that the U direction is the direction in which the light converting portion 22 moves along the X direction, and the V direction is the direction that the light converting portion 22 rotates around the X direction.

FIG. 12 is a simulation result of the deviation rate of the U-direction and V-direction Hall sensors in the related art. FIG. 13 is a simulation result of the deviation rate of the Hall sensor in the U direction and the V direction in the present application. Among them, the horizontal axis is the deviation rate, and the vertical axis is the number of samples that fall into the corresponding deviation rate. Deviation rate (%)=((actual value – center value)/range of Hall sensor)×100%. The range of the Hall sensor is in the range of ±1.5°.

It can be seen from FIG. 12 and FIG. 13 that, compared with the prior art, the data in the V direction are more concentrated in the present application, that is, the deviation rate is smaller. Further, the present application can reduce the deviation rate of the Hall sensor in the V direction to one thousandth of the deviation rate of the prior art.

Referring to FIG. 11 , the first electromagnetic element 282 is disposed on the bottom wall 216 . The first electromagnetic element 282 is annular, the first electromagnetic element 282 has a first center line 2821 , and the inductive element 281 is disposed away from the first center line 2821 . The distance A between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 ranges from 0.5 mm to 1.0 mm.

When the distance A between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 is in the range of 0.5 mm to 1.0 mm, the shifted initial value is suitable. It can be understood that the initial value after offset cannot be too small, so that the deviation rate cannot be reduced more; the initial value after offset cannot be too large, which will lead to insufficient range of the Hall sensor.

Preferably, the distance between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 is 0.75 mm.

In another example, the distance A between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 is 0.5 mm; The distance A of the center line 2821 is 0.8 mm; in another example, the distance A between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 is 1 mm. The specific value of the distance A between the center of the induction element 281 and the first center line 2821 of the first electromagnetic element 282 is not limited herein.

It can be understood that the first electromagnetic element 282 can also be in a circular, square or any other shape, and the specific shape of the first electromagnetic element 282 is not limited herein.

In addition, in the example of FIG. 11 , the inductive element 281 is located on one side of the first electromagnetic element 282 , it can be understood that in other examples, the inductive element 281 may be located on the other side of the first electromagnetic element 282 . As long as the sensing element 281 does not interfere with the existing structure of the first imaging module 20 , the specific position of the sensing element 281 is not limited herein.

The first electromagnetic element 282 has a second centerline 2822, the second centerline 2822 is perpendicular to the first centerline 2821, the second centerline 2822 and the first centerline 2821 intersect at the center of the first electromagnetic element 282, and the inductive element 281 is The number is two, and the two induction elements 281 are symmetrically arranged with respect to the second center line 2822 of the first electromagnetic element 282 .

In this way, the data measured by the first electromagnetic element 282 can be made more accurate. Specifically, the data output by the two first electromagnetic elements 282 may be calculated, for example, averaged, so as to obtain more accurate data. In addition, when one of the first electromagnetic elements 282 is abnormal, the other first electromagnetic element 282 can also be used to ensure the normal operation of the optical anti-shake, which is beneficial to improve the reliability of the driving device 28 .

Of course, in other examples, the number of sensing elements 281 may also be 3, 4 or any other number, and the specific number of sensing elements 281 is not limited here.

The third magnetic element 283 is provided on the light converting element 12 . Specifically, the third magnetic element 283 is disposed on the mounting portion 23 , and the first electromagnetic element 282 cooperates with the third magnetic element 283 to drive the light turning element 12 to rotate around the first rotating shaft 103 .

In this way, by driving the mounting portion 23 to rotate, the light-changing portion 22 can be rotated, thereby realizing optical image stabilization. Specifically, after the sensing element 281 detects the rotation angle, the processor can determine the voltage that should be applied to the first electromagnetic element 282 according to the data, the first electromagnetic element 282 generates a magnetic field after the voltage is applied, and the third magnetic element 283 is subjected to the magnetic field. Therefore, the mounting portion 23 is driven to rotate to compensate for the shaking of the first imaging module 10 . This enables optical image stabilization.

A gap 284 is formed between the sensing element 281 and the third magnetic element 283 . The dimension B of the gap 284 is in the range of 0.20mm-0.25mm, as shown in FIG. 5 .

In this way, the space for the third magnetic element 283 and the mounting portion 23 to rotate can be avoided, and it is ensured that the third magnetic element 283 and the mounting portion 23 will not interfere with the sensing element 281 during the rotation. Specifically, gap 284 is an air gap.

Preferably, dimension B of gap 284 is 0.22 mm. In another example, the dimension B of the gap 284 is 0.20 mm; in yet another example, the dimension B of the gap 284 is 0.21 mm; in yet another example, the dimension B of the gap 284 is 0.25 mm. The specific value of the dimension B of the gap 284 is not limited here.

The driving circuit board 285 is provided in the lens barrel. Further, the driving circuit board 285 is disposed on the bottom wall 216 . The first electromagnetic element 282 and the induction element 281 are both disposed on the driving circuit board 285 . That is, the first electromagnetic element 282 and the induction element 281 are disposed on the bottom wall 216 through the driving circuit board 285 .

In this way, while ensuring that the driving circuit board 285 supplies power to the first electromagnetic element 282 , the structure of the first imaging module 20 can be made more compact, which is beneficial to the miniaturization of the first imaging module 20 . Specifically, the driving circuit board 285 may be a flexible circuit board, a printed circuit board or other types of circuit boards.

The driving circuit board 285 may be attached to the bottom wall 216 by welding, bonding, or the like. In one example, the driving circuit board 285 may be attached to the bottom wall 216 by tape.

During the assembly process, the first electromagnetic element 282 and the induction element 281 can be fixed to the driving circuit board 285 first, then the driving circuit board 285 can be attached to the bottom wall 216 , and finally the bottom wall 216 can be assembled to the housing 21 . In this way, it is simple and convenient, and the assembly efficiency can be improved.

It should be pointed out that the driving circuit board 285 is disposed on the bottom wall 216 of the lens barrel. It may mean that the driving circuit board 285 is fixed in contact with the bottom wall 216 of the casing 21 , or it may mean that the driving circuit board 285 is fixedly connected to the bottom wall 216 of the casing 21 through other components.

The second electromagnetic element 286 is provided on the side wall 214 . As shown in the orientation in FIG. 7 , the second electromagnetic element 286 is disposed on the side wall 214 in the X direction of the lens barrel. The fourth magnetic element 287 is provided on the mounting portion 23 . As shown in the orientation in FIG. 7 , the second electromagnetic element 286 is provided at the position of the mounting portion 23 in the X direction. The fourth magnetic element 287 cooperates with the second electromagnetic element 286 to drive the light turning element 12 to rotate around the second rotating shaft 104 .

In this way, the fourth magnetic element 287 cooperates with the second electromagnetic element 286 so that the first imaging module can realize the optical anti-shake effect in the X direction. The second electromagnetic element 286 is, for example, a coil. The fourth magnetic element 287 is, for example, a permanent magnet.

In this embodiment, the number of the second electromagnetic elements 286 is two, which are respectively disposed on the two side walls 214 of the lens barrel in the X direction. Correspondingly, the number of the fourth magnetic elements 287 is two, which are respectively disposed on both sides of the mounting portion 23X in the direction. The two second electromagnetic elements 286 cooperate to drive the light-turning portion to rotate around the second shaft 104 . The electromagnetic quantity formed by the two second electromagnetic elements 286 can be calculated by difference, so as to accurately control the rotation angle of the light diverter.

In this embodiment, the housing 21 is a protective element of the first imaging module 20 , which can reduce the impact on the first lens assembly 24 . In the present embodiment, the casing 21 has a substantially rectangular parallelepiped shape. The housing 21 is connected to the lens barrel 11 . Further, the housing 21 and the lens barrel 11 are integrally formed. In other words, the periscope lens 10 is integrated into the first imaging module 20 . Of course, in other embodiments, the housing 21 and the lens barrel 11 are separate structures.

Referring to FIG. 5 , the first lens assembly 24 is accommodated in the loading element 25 , and further, the first lens assembly 24 is disposed between the light converting portion 22 and the first image sensor 26 . The first lens assembly 24 is used to image incident light on the first image sensor 26 . In this way, the first image sensor 26 can obtain images with better quality.

The first lens assembly 24 can form an image on the first image sensor 26 when it moves as a whole along its optical axis, so as to realize the focusing of the first imaging module 20 . The first lens assembly 24 includes a plurality of lenses 241. When at least one lens 241 moves, the overall focal length of the first lens assembly 24 changes, so as to realize the zoom function of the first imaging module 20. More, it is driven by the driving mechanism 27 The loading element 25 moves in the housing 21 for zooming purposes.

In the example of FIG. 5 , the loading member 25 is cylindrical, and the plurality of lenses 241 in the first lens assembly 24 are fixed in the loading member 25 along the axial interval of the loading member 25 . In the example of FIG. 14 , the loading element 25 includes two clips 252 that sandwich the lens 241 between the two clips 252 .

It can be understood that, since the loading element 25 is used to fix a plurality of lenses 241, the required length of the loading element 25 is relatively large, and the loading element 25 may be a cylindrical, square, or other structure with a cavity. In this way, the loading element 25 is cylindrical, and the loading element 25 can better set a plurality of lenses 241 , and can better protect the lenses 241 in the cavity, so that the lenses 241 are not easily shaken.

In addition, in the example of FIG. 14 , the loading element 25 clamps the plurality of lenses 241 between the two clips 252 , which not only has a certain stability, but also reduces the weight of the loading element 25 and reduces the driving force of the driving mechanism 27 The power required for the loading element 25 and the design difficulty of the loading element 25 are relatively low, and the lens 241 is also easier to set on the loading element 25 .

Of course, the loading element 25 is not limited to the above-mentioned cylindrical shape and two clips 252. In other embodiments, the loading element 25 may include three, four, etc. more clips 252 to form a more stable structure. , or a simpler structure such as a clip 252 ; or a rectangular body, a circular body, etc., with a cavity to accommodate various regular or irregular shapes of the lens 241 . On the premise of ensuring the normal imaging and operation of the imaging module 10, the specific selection can be made.

The first image sensor 26 may use a complementary metal oxide semiconductor (CMOS, Complementary Metal Oxide Semiconductor) photosensitive element or a charge-coupled device (CCD, Charge-coupled Device) photosensitive element.

The driving mechanism 27 is an electromagnetic driving mechanism, a piezoelectric driving mechanism or a memory alloy driving mechanism.

Specifically, when the driving mechanism 27 is an electromagnetic driving mechanism, the driving mechanism 27 includes a magnet and a conductor, the magnet is used to generate a magnetic field, and the conductor is used to drive the loading element 25 to move. When the magnetic field moves relative to the conductor, an induced current is generated in the conductor, and the conductor is subjected to an ampere force to drive the loading element 25 to move.

When the driving mechanism 27 is a piezoelectric driving mechanism, a voltage can be applied to the driving mechanism 27 based on the inverse piezoelectric effect of the piezoelectric ceramic material, so that the driving mechanism 27 generates mechanical stress. That is to say, through the conversion between electrical energy and mechanical energy, the driving mechanism 27 is controlled to mechanically deform, thereby driving the loading member 25 to move.

When the drive mechanism 27 is a memory alloy drive mechanism, the drive mechanism 27 can be made to memorize a preset shape in advance. When it is necessary to drive the loading element 25 to move, the driving mechanism 27 can be heated to a temperature corresponding to the preset shape, so that the driving mechanism 27 returns to the preset shape, thereby driving the loading element 25 to move.
